I wanted to replace my old pin push where the brass barrel had split during use, but this tool seems to be almost unobtainable in a good quality option.I was wary of buying this as it is all plastic, but having used it several times it seems pretty robust, I thought I would give it 4 stars as I do think it would be more prone to damage and would have preferred a brass one as the last one lasted me 10 years or so however this is good value so I have gone for the 5 star rating based on the price.Out of interest I suspect what damaged my old one was someone borrowed it, (more fool me for lending it!) and may have used a very thin pin as they can slide up and get jambed between piston and sleeve. Worth remembering when selecting pins to use with a push.
